From b235edce5cbe4e978d44d8c57ec15afc4ba27d50 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Mon, 20 Apr 2015 09:20:41 +0000 Subject: [PATCH] ath10k: fix qca61x4 hw2.1 support commit 11a002efbaa7fbd9f6e616695ab42aa9f1caf060 upstream. During initialization firmware does some sort of memory switch between DRAM and IRAM. If configuration value for bank switching isn't correct device crashes during init. The new value prevents firmware 11.0.0.302 (and possibly others) for qca61x4 hw2.1 from crashing during init.
